Abstract

This dataset consists of scanning electron micrographs accompanied by microconstituent annotations, and is intended as a community benchmark dataset for microstructure segmentation and clustering tasks. The dataset consists of two groups of ultrahigh carbon steel (UHCS) micrographs: a set of images with broad field of view that contain complex microstructural features (proeutectoid grain boundary cementite network, spheroidite particles, Widmansttaten lath), and a higher-magnification set of images originally collected to quantify the cementite particle size distribution.
